Features and Commands
Base Feature The first feature that is created. The foundation of the part. The base feature geometry for the box is an extrusion. The extrusion is named Extrude1.
Tip: Keep the base feature simple.
3
Sketch the 2D profile
To Create an Extruded Base Feature:
1. Select a sketch plane.
2. Sketch a 2D profile.
3. Extrude the sketch perpendicular to sketch plane.
Select the sketch plane

Features Used to Build Tutor1
Extruded Boss Feature
– Adds material to the part.
– Requires a sketch.
Extruded Cut Feature
– Removes material from the part.
– Requires a sketch.
Fillet Feature
– Rounds the edges or faces of a part to a specified radius.
6
Features Used to Build Tutor1
Shell Feature
– Removes material from the selected face.
– Creates a hollow block from a solid block.
– Very useful for thin-walled, plastic parts.
– You are required to specify a wall thickness when using the shell feature.
7
Magnify or reduce the view of a model in the graphics area.
Zoom to Fit – displays the part so that it fills the current window. Zoom to Area – zooms in on a portion of the view that you select
by dragging a bounding box. Zoom In/Out – drag the pointer upward to zoom in. Drag the
pointer downward to zoom out. Zoom to Selection – the view zooms so that the selected object
fills the window.

View Orientation
The views most commonly used to describe a part are:
– Top View– Front View– Right View– Isometric or
Trimetric View
13
Default Planes
Default Planes– Front, Top, and Right
Correspond to the standard principle drawing views:– Front = Front or Back view
– Top = Top or Bottom view
– Right = Right or Left view
14
Isometric View
Displays the part with height, width, and depth equally foreshortened.– Pictorial rather than orthographic.
– Shows all three dimensions – height, width, and depth.
– Easier to visualize than orthographic views.
15
Section View
Displays the internal structure of a model.
Requires a section cutting plane.

The Status of a Sketch
Under defined– Additional dimensions or relations
are required.– Under defined sketch entities are blue (by default).
Fully defined– No additional dimensions or relationships
are required.– Fully defined sketch entities are black (by default).
Over defined– Contains conflicting dimensions or
relations, or both.– Over defined sketch entities are red (by default).
17
Geometric Relations
Geometric relations are the rules that control the behavior of sketch geometry.
Geometric relations help capture design intent.
Example: The sketched circle is concentric with the circular edge of the extruded boss feature.
In a concentric relation, selected entities have the same center point.
18
Geometric Relations
The SolidWorks default name for circular geometry is an Arc#.
SolidWorks treats circles as 360° arcs.
